What good does it do you to keep it on the rifle if it isn't holding zero? Why not send it off for repair if it won't make the shots you need to dispatch a yote? Does the Trophy line have a warranty now that will be cheaper than the replacement cost?
Why not remount it and do the tap test? You are tapping it, not beating it with a sledgehammer, though I've had some scopes, no names, that might have been the best answer to.
